How to use manage_screen-id_columns filter in WordPress

manage_screen-id_columns filter

The dynamic portion of the hook name, $screen->id, refers to the ID of a specific screen. For example, the screen ID for the Posts list table is edit-post, so the filter for that screen would be manage_edit-post_columns.

To use manage_screen-id_columns filter, first you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at WePlugins, always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function modify_manage_screen-id_columns_defaults which takes 1 parameters and we registered using add_filter. The first parameter manage_screen-id_columns is name of the hook, The second parameter modify_manage_screen-id_columns_defaults is name of the function which need to be called, third parameter is the priority of calling the hook if same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometime, you have to remove a registered hook so you can use remove_filter to remove manage_screen-id_columns filter.

Parameters

    }
